Also, don't forget to grab a Magnet-Scrubber. Those things have saved me an unbeleivable amount of time, just don't let your fingers get cought on them before you put 'em in the tank.
As for plecos creating more algae, I disagree. I've always kept at least one pleco in my oscar-only tanks, and they make a world of difference. This is, at least, with oscars only, a VERY MESSY fish itself.
